310 SS Round Bar
Product Description
310S Polished Stainless Steel Rod is a low carbon version of 310 stainless steel (carbon content ≤ 0.08%). It is processed by cold drawing, polishing or bright annealing. It has high temperature resistance (up to 2010°F/1100°C), excellent corrosion resistance and good weldability. It is suitable for precision parts that need frequent welding in high temperature environments.

FAQ
Q: What is the difference between 310S and 310 stainless steel?
A: 310S has a lower carbon content (≤0.08%) and does not require annealing after welding, making it suitable for high-temperature scenes that require frequent welding.
Q: Can 310S stainless steel cold-rolled bars be used in seawater environments?
A: It can resist seawater corrosion in the short term, and it is recommended to choose 316L or SMO 254 with a higher molybdenum content for the long term.
Q: How does surface polishing affect corrosion resistance?
A: Polishing reduces surface defects, reduces the adhesion of corrosive media, and improves pitting resistance.
